The stock market's run will result in either a 20 percent correction or a more nasty sell off at some point this year, Marc Faber, publisher of the Gloom Boom and Doom report, told CNBC's "Closing Bell" on Thursday.
Faber pointed out that it's been almost exactly four years since the stock market bottomed out. "We're up very substantially, I think investors who today rush into stocks should be reminded of that," he said.
He sees two possible scenarios. Either a 20 percent correction for stocks and then a move higher, or a scenario that is similar to 1987 or 2000 when stocks rise strongly early in the year only to drop sharply.
